The numerical solutions were carried out using commercial CFD code FLUENT 6.0. The problem of modelling highly swirling flow is overcame by means of an algebraic turbulence model, and all the features of the experimentally observed gas flow in a cyclone are shown to be computationally reproduced. It was found that CFD simulations predict excellently the axial and tangential velocity with an average deviation of ± 0.5 m/s from the presented experimental data. The physical mechanism for prolonged cyclone cylindrical body and vortex finder has also been successfully elucidated. Specifically, results obtained from the computer modelling exercise have demonstrated that CFD with RSM turbulence model is suitable for modelling a flow field and hydrodynamic of cyclone. 2011-09-04T04:50:06Z 2011-09-04T04:50:06Z 2009-06 Article The Journal of the Institution of Engineers, Malaysia, vol. 71(2), 2009, pages 51-58 0126-513X http://www.myiem.org.my/content/iem_journal_2009-180.aspx http://hdl.handle.net/123456789/13650 en The Institution of Engineers, Malaysia |
